GREASE-CUP.

Specication of Letters Patent.

Application led J'une 5, 1914. Serial No. 843,243.

To all whom t may concern l Y Be it' known that we, MICHAEL LoUIs HENRY and MICHAEL HENRY, citizens of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have invented new and useful Improvements in Grease-Cups, of which the following is a specication.

This invention relates to grease cups and is in the nature of an improvement upon and simplification of the patent granted to Michael Henry, #1,012,546, dated December 19, 1911.

The object of the present invention is to provide simple" and reliable means which will facilitate the application of the cap to the cup and at the same time facilitate the refilling of the cup with grease, also insuring the retention of the cap upon the cup and the proper operation of the expressing plunger.

With the above and other objects in view, the invention consists in the novel construcas will be hereinafter more fully described, illustrated and claimed.

In the accompanying drawings z-Figure 1 is a perspective view of the complete cup of this invention ready for application to any bearing. Fig. 2 is a diametrical section through the complete cup in line with the vertical portions of the locking groo-ves. Fig. 3 is asimilar view taken in line with oppositely located notches. Fig. 4 is a side elevation of the cup omitting the cap. Fig. 5 is an inside fragmentary view of the cap, showing one of the locking lugs.;l Fig. 6 is a plan view of the cup omitting the cap. Fig. 7 is a detail perspective view of the cap spring.

Referringy to Lthe drawings 1 designates the cup proper which is in the form of a hollow cylindrical body eXteriorly threaded at 2 to enable it to be screwed into place, and having a jamb nut 3 formed with notches 4 to facilitate tightening the same.

Both ends of the cup are left open to receive and discharge the grease and over the upper end of the cup is tted a ianged cap 6 which is adapted to be turned manually on the cup` and also moved upwardly or downwardly for the purpose of attaching and detaching the cap as will presently appear. Adjacent toits upper end the cup 1 is provided at diametrically opposite places with bayonet grooves each comprising a vertical or upright portion 7 and a portion 8y yextending perpendicularly to the portion 7 of an elbow which is slightly curved as'- shownat 9 to facilitate the application of the cap to the cup and the removal of the same therefrom. The upright portions 7 of the grooves intersect the top edge of the cup so as to receive the locking lugs of the cap hereinafter referred to. The portion 8 of said grooves is also provided with the eXtension notches 10 along the upper side thereof, the purpose of which will appear.

Mounted for movement longitudinally within the cup 1 is a plunger 11 for eXpress-' ing the grease from the cup and extending upwardly from said plunger is a plunger stem 12 .which is slidable through an opening 13 in the center of the cap r6, a helical spring 14: encircling the stem l2 and bearing at one endagainst the plunger 11 while the opposite end thereof is seated against a longitudinally bowed cap retaining spring 15 the central portion of which is formed with a hole 16 to receive the plunger stem and the opposite ends of which bear against the top edge of the cup 1 at diametrically opposite points. Centrally the spring 16 bears against the inside wall of,k thegtop ofthe cap 6 so that said spring" exerts anv outward pressure against the cap for retaining the same in place on the cup and preventing the cap from jarring loose.

Internally the cap 6 is provided with diametrically opposite locking lugs 17 which are movable in the grooves in the cup, said lugs 17 being provided on their upper sides with rounded bosses 18 of the same shape as the notches 10 above referred to, Vthe bowed vspring 15 serving to hold the bosses 18 in engagement with the notches 10, thereby preventing the cap from turning either axially or moving longitudinally with respect to the cup so as to accidentally jarV The cap is removed by giving a partial Vturn oraXial vmovement thereto andthenY the notches 10. Thereafter the spring 15,

serves to hold the cap'locked on the cup and the plunger is then pushed forward by the spring soA as to deliver` the grease to the bearing.; f j n The construction above described provides a labor'and trouble savingV cup, the cap ,of which may be instantly removed `and replaced and when the cap is in place it prevents the grease from escaping from thev cup so as to catch dirt and. soil the clothing. Only one adjustment is necessary to remove the cap and plunger and to return the same to their useful positions, The plunger automatically forces vthe grease from the cupV in accordance with the feed governed by the position ofthe regulating screw and the movement of the grease is constant and even. A glance at the `cup shows whether 'or not it is empty and enables aquick estimate to be made as to how inuch grease remains the cup. The cup will last as long as an engine, there being no threads to strip orY Wear out. Italso eifects a saving of grease,

an elimination of dirt, a rbetter and even` lubrication of the bearing with which it is associated and is of general convenience and utility. i What we claim is c 1 l. The combination of detachable lcap therefor, one of said members being formed with oppositely located bayonet grooves having extension notches, lugs on theother member movable into and out of said grooves and notchesby a combined aX- ial and sliding movement, an expressing plunger in said cup, a plunger stem slidable through ysaid cap, a spring arranged to Copies of this patent may Y'ne obtained for p nisvas Vpress Ysaid plunger toward the rdischarge end ofthe cup, and a bowed spring inter-V posed between said cup and cap and pierced by said plunger stem serving to retain the cap on the cup.

2. rlClie combination of a cup formed near" the receiving end thereof with oppositely located bayonet grooves, a detachable cap fitting around the upper portion of said cup, lugs on the inside of said cup and movable into and out of said'grooves by accombined axial and sliding movement, an eX- pressing plunger in said cup, a plunger stem slidable through said cap, a springar-l rangedpto press said plunger toward theV discharge vend of the cup,fand a bowedv spring interposed between said cup and cap serving to retain thel cap onthe` cup, said' bowed spring forming a seat for the plun# ger spring. Y Y

3. Thecombination of a cupV formed near the receiving end thereof with oppositely located bayonet grooves having extensiony notches along the upper sides thereof, a

detachableI cap fitting around the upper V portion of said cup, lugs Von the inside ofk ksaid cap and movable into andvout of said grooves by a combined aXial and sliding movement also adapted to seat in said a spring arranged to press said plunger toward the discharge yend of the cup, and a bowed spring interposed between said cup and cap serving to retain the cap on the cup, said lbowed spring forming a seat VVfor the plunger spring. y

In testimony whereof wev ahX our signatures'in presence of two witnesses.
